Superscalar extension for the MULTRIS processor

The MULTRIS (MULTitasking RISC) is a RISC-type processor developed at George Mason University and targeted for multitasking languages. The paper extends the previous design of the GMU MULTRIS processor, by providing it with a deeper pipeline and with instruction level parallelism (ILP) capability. The design is modified for several versions of superscalar operation: two-issue, three-issue, and four-issue. A detailed design extension for the above options is presented and discussed. A significant improvement in performance, compared to the earlier design can be attained.
